Those are basically the only decks that counter it (hope does too though). I have no problem with aether though because I take some explosions. And I think devourers are bugged because as far back as I remember (months), every game I'd play against them while I used a deck that used a mark for splash, 80% of the time their one early pest would take the mark quanta. Some people would say it's just bad luck or I'm seeing something that's not really there, but it's happened in the vast majority of the games I've played.
That being said, RoL's + Cremate are all you need to beat a devourer deck. Or use towers.
